Be it known that I, WILLIAM R. SCOTT, a citizen of the United States,residing at Fort Vorth, in the county of Tarrant andState of Texas, haveinvented certain new 4and usefl Improvements in Ballast-Spreading Cars,of which the following is a specification;

The invention relates to that kind of ballast-spreading cars which areadapted to level, scrape, or plow the ballast over and into tinalposition, and particularly to that class of cars which are arranged toscrape the ballasting material from the embankments at each side ofthetrack toward the center and spread it between the rails and sleepers,all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple,economical, and eiiicient ballast-spreading car. i

A further object is to provide a ballastspreaderof the class describedwith scraping and leveling mechanism for moving the ballasting materialfrom the embankment at each side ot' the tracks` over and between th'ecenter of the tracks. V

A further object is to provide a ballastspreading car with Scrapers,plows, or levelers for moving the material from the outside to thecenter of the track and foldably arranged thereon so as to be folded orcollapsed into an inoperative position and expanded or opened into anoperative position.

Further objects will appear from an examination of the drawings and thefollowing description and claims.

The invention consists principally in the combination of a car providedwith a set of plows arranged underneath the same and extending from apoint outside the tracks toa point inside the tracks to scrape or moveballasting material from the outside into and between the tracks.

The invention consists, further, in the combination of a car, plowmechanism attached thereto below the car and at each side thereof, withthe `forward ends arranged outside ot' thesupporting-wheels andinclininginwardly and backwardly to a point or points inside of such wheels tomove material from the outside of the tracks to the inside over andbctweeu the tracks.

the supporting-wheels and extending backwardly and inwardly to a pointinside such wheels and providing an open space between the rear innerends, with means for foldably securing such mechanism to the car wherebyit may be removed from or placed in operative position.

The invention consists, further, in the features, combinations, anddetails of construction hereinafter described and claimed.

side of the plow, partly in section, looking at it from the inside andshowing a detailot' its supporting and pressing mechanisms.

In the art to which this invention relates it is well known that thereare several types of cars which carry ballast arranged for dischargingthe same adjacent to the railroadtracks, one type a special one whichprovides for dumping the ballast in piles between the tracks, so that itmay be afterward spread economically either by manual labor orspecially-designed mechanism. This type of car, however, is a specialone and is only adapted, so far as now used, for the carrying of ballastand is not used at any other times. It will be seen, therefore, that arailroad whichis equipped with this special type of ballast-car, whichcan only be used for this purpose and at certain times, means,necessarily, a large and expensive addition to the rolling-stock of suchrailroad and for which very small returns are received. A second and themost prominent type is the platform .or side-dumping car, which dumpsthe ballast or similar material to each side of the track onto what iscalled the embankment. The re` is no special machinery designed forsuccessfully handling-that is, inovingand spreadingthe ballast over andbetween the tracks in such a manner as to prepare it for the jacking-upand tamping of the sleepers which support the tracks. The result is thatmanual labor has to be entirely depended on for the shoveling of thematerial over and between the tracks and afterward spreading it intoposition, all of which consumes considerable time and involves greatexpense. Myinvention, therefore, is intended to provide aballast-spreading car of such construction and arrangement as will takematerial (lumped at either or both sides ot the track, move it over andbetween the tracks, and spread it into such position as will permit ofthe ties being jacked up or tam'ped in with the least expenditure oflabor and time, all of which will be thoroughly appreciated by thoseskilled in the art. In illustrating and describing these improvements Ihave ouly'llustrated and described that which I consider' to be new,taken in connection with so much that is old as willproperly disclosethe invention to others and enable those skilled in the art to practicethe same, leavin?` out of consideration otherand well-known elements,which if illustrated and described herein would only tend to confusion,prolixity, and ambiguity.

In constructing my improvements I prefer to provide a car provided witha platform a, constructed and arranged in the usual man-'nerofplatform-carsand supported and moved platform-cars, all of which'is thoroughly understood' by those skilled in the art and needs nofurther or detailed description here.

rward strai n.

In order to provide means for scraping or moving the ballast from theoutside of the track d (see Fig. 18) to a pointV over and loetween thetracks and level the same, a pair of scraping-plows e is provided, oneat each side of the track and underneath the platform of the car andextending from a point forward of the car and outside thesupporting-wheels inwardly and rearwardly to a point between the track,leaving a space, as shown vin Fig. 18, between the rear ends thereof. Anexamination of the drawings will show that as the plows are movedforward in the manner 4hereinafter described the ballast material iscaught up, scraped, and moved inwardly between the track, leveling aportion of the same outside of the track to cover up the ends of thesleepers, while the residue is left in a pile between the tracks to bescrapedand leveled in a manner hereinafter described. In Figs; 3, 9,10,and 1l the construction and shape of the forward plows are clearlyshown, and fromy such figures it will be seen that the forward end ofthe plow is much wider than the rear end, and its lower edge iscurvedinwardly, so as to scrape up the material, muchlike a shovel, and throwit inwardly to a position between the tracks, where the straight,narrow, and rear part of the plow levels a portion of the ballast andcontinues the further inward movement of the residue. It will beunderstood by those skilled in the art that it is highly desirable thatthis plow mechanism be moved out of the way when it is not in use, sothat the car may be moved from one point of the road to another withoutany danger of destroying its efficiency. In order to accomplish thisresult, each of such plows is provided with upright plow-beams f,arranged atthe outside thereof, extending upwardly and terminating inrectangular frame p0rtions g at the upper ends thereof. Theserectangular frame portions are adjustably secured to'beams orarms h,which are pivoted to the platform of the car at t' (see Fig. 7) andyextend outwardly from each side thereof.

To adj ustably secure these plow-beams to the swinging beams abovedescribed, a pair of U.- shaped bolts ,7' is provided and passed throughclips 7c, detachably secured to the swinging beams and which extenddownwardly and are provided at their lower free ends with wheel-nuts Z,having threaded engagement therewith. These wheel-nuts are arranged tocontact straps m, extending acrossthe ends of each of the bolts andcontacting blocks n, interposed between the straps and the rectangularframes of the plowbeams, so as to clamp such beams firmly between themand the outwardly-extending swinging b eams. As the strain on this frontpair of plows when they are in use extends toward the outside of thecar, it becomes desirable to provide means to resist such out- In orderto accomplish this result, a pair of chains o is provided, one end ofeach of which is secured to each plow-beam IOO IIO

and the other end passed around a drum p. The drum is provided with avertically-arranged shaft g/,rotatably mounted in the frame portion ofthe car, as shown in Fig. 7, and provided witha wheel or handle r at itsupper end and also with a ratchet s and pawl t, (see Fig. 5,) soconstructed and arranged that the operator can wind up the chain to thedesired tension and lock the mechanism in such position as to resist theoutward strains on the plows.

In order to offset or compensate for the rear ward strain on the plowswhen in use, a pair of stay-rods u is provided, one end of each of whichis pivotally secured to the forward end of the car, as shown in Fig. 2,and the other secured to a clevis n on the upright plowbeam, as shownparticularlyin Figs. 2 and 5.

These stay-rods are made in two or more parts hinged together at m, onepart of which, as shown in Fig. 3, has a turnbuckle w, all arranged soas to efficiently support the plows in operative position to resist therearward strains incident to their use and at the same time permit suchplows and their attached mechanisms to be folded upwardly and backwardlyout of the way, as will be more fully hereinafter set forth.

As has been hereinbefore described, the mechanisms which hold the plowin use are foldably secured in position, and it becomes desirable,therefore, that some means be provided to lock them in their open oroperative position. To accomplish this, the plow is provided with asupplementary L-shaped plowbeam y, adjustably secured at its free end tothe plow, as shown particularly in Figs. 3, 5, and l2, and at the otherend pivotally secured at ,zto angle-irons on each side of the car.lVhen'the parts are in their open, down, and operative position, thesesupplementary beams fg pass between a pair of outwardlyextending arms20, which in turn are provided at their outside end with projecting lugs2l. (See Figs. 5 and 13.) The supplementary beams are passed betweenthese outwardly-extending lugs, as described, and afterward a slottedlocking-plate 22 is dropped into engagement with the lugs on thelockingarms 20, and t-hus lock the parts in the position shown in Fig.13.

From the foregoing description of construction and operation and anexamination of the drawings it will be seen that the plow and itssupporting parts are foldably secured to the platform-car, so that theymay be moved upwardly and folded back into inoperative positions and outof the way of passing trains. An examination of Fig. 7 will show thatunless some means be provided for moving the plow-beams inwardly theouter edges thereof will be folded backwardly to a point or pointsbeyond the center of the car, and thus interfere with each other. Itbecomes necessary, therefore, to secure the supporting-beams to theswinging beam in an adjustable mannerthat is, that they be permitted tomove inwardly the desired amount. complish this result, the clips 7c aresecured to the swinging beams h, above described, which beams areprovided with a plurality of holes 23, so that the securing-bolt of suchclips may be removed and the clip, with the U-shaped bolts, movedinwardly. The securing-bolts are then passed through another one of theholes 23, thus permitting the plowbeams' to move inwardly, so that thebeams and supporting-arms may be swung upwardly and inwardly without anyinterference, as shown in Fig. 8. lVhen such folding operations areabout to take place, the operative releases the ratchet and pawl s andt, above described, so as to permit the chain o to also move, andthereby permit the mechanisms to be folded, as above described. It willalso be remembered that as a prerequisite to the movement of these partsthe locking-plate 22 must be removed from its locking position. Theselocking-plates are secured to chains 24, one end of which is secured toa crossbeam on the platform of the car, so that they always keep suchlocking-plates in position for use.

As the plows'and their attached mechanisms are very heavy, it will bepractically impossible to move them out of or into position unless alarge and unnecessary number of operatives are employed. It thereforebecomes desirable, and in fact necessary, that mechanism be provided toaccomplish this result.

In order to provide mechanism by which thel plows may be raised fromtheir inoperative position and lowered into their operative position, acrane 25 is provided, the upright post of which is pivoted in theplatform of the car at its lower end and in a longitudinal beam 26 atits upper end. This longitudinal beam is supported upon trussed uprights27, arranged at or near each end of the car. The crane is provided witha winding-drum 2S, operated by means of the spur-gear and pinion 29 and30, the latter by means of the crank-handles 3l. The drum is furtherprovided with a cable 32, the free end of which carries a hook 33,arranged to engage with a ring 34 on each end of the plows, so` that asthe drum is rotated in one position each plow may be alternately movedinto or out of position or moved outwardly and held suspended, so as todrop back into operative position, the parts being so constructed andarranged that only two men are necessary to operate the car and handle alarge amount of ballast.

It is highly desirable that some means be provided to assist the forward`pair of plows in the distribution and complete the leveling of theballastin g material between the tracks. Such plows, however, may beconstructed and arranged to handle practically all of the ballast; butfor purposes of economyit is desirable that a supplementary plow 35 beprovided, arranged at the rear end of the car and supported upon avertical shaft 36. (Sec In order to ac- IOO IIO

'downWardlyprojecting portions 37, which span each rail, provide aclearance inside and outside of each of the tracks to provide clearancefor the car-wheels and flanges thereof, so that the danger of derailingis minimized. This supplementary plow is efficiently held v in positionbyv means ot the forwardly-extending stay-rods 38 and therearwardly-extending stay-rods 39, which are secured to 'the plow, asshown particularly in Fig. 14,

and assist it in'withstanding the strains and stresses incident to use.A supporting-post 36 for this supplementary plow is provided andyieldingly held in position by means of a tension-'spring40, which isinterposed between a strap 4l, surrounding the post, and a collar 42 onsuch post,lthe spring acting to always ho1d the plow at'its lower limirIof motion. The upper end of this post is provided with a clevis 43,pivotally secured thereto, so that when it is desired to move the carthe hook 33 on the cableof the crane may be engaged therewith and thecrane operated to raise such plow against the pressure of itstension-spring and out of the way, so that the car maybe moved fromplace to place whenever desired.

From the foregoing it will be seen that the pair of forward plows areadjustable as to width and that it often becomes desirable to adjustthem up and down to accommodate tracks that are Araised and lowered. Insuch event all that is necessary is to remove the blocks 44, (shown inFig. 7,) which are arranged between the rectangular frames of theplowbea1ns and the swinging beams, and place blocks therein of thedesired thickness,

which of course will regulate or adjust the.

position of the plows vertically.

As shown in Fig. 18, it will be seen that the ballast in such ligure isdumped outside of the' tracks at the embankments, so that the forwardpair of plows contact such material, scrape, shovel, and throw it overand between the tracks, leveling a portion thereof, the residue betweenthe tracks being operated upon by the supplementary rear plow,

which afterward scrapesv and levels it into proper position. y

There are many advantages incident to a ballast-levelin g carconstructed in accordance with these improvements, the principal onebeing that any kind of a car may be used for the carrying and dumping ofmaterial outside of the tracks, thereby saving the railroad orcontractor the expense of purchasing and maintaininga large number ofspecial cars. VA further advantage is that it can be dle'practically anyamount of ballast which can'be dumped'at the embankments and scatter itover and between the tracks, as desired. Further advantages will be seenby those skilled in theart from an examination of the drawings and theforegoing description.
